I have insufficient knowledge to debug what goes wrong with remote desktop software. However, if you have text console, or ssh, or serial console, then you can post logs and this should be useful in knowing what is going wrong. Quite possibly the original desktop software was replaced or configured incorrectly, and logs may help.
Among all of the methods of access, the serial console will be preferred since this can show even boot stages prior to Linux starting. This software has no requirements for video or networking. See:
If you can get a boot log (serial consoles can log), this would be preferred. If not, then after boot the “dmesg” output would be nearly as useful.
Additionally, run the command “ls -ltr /var/log/X*.log”. The last file listed will be the most recently updated log for the desktop graphics (probably “Xorg.0.log”, but since things didn’t work, this may not be the case). You can rename this with a “.txt” extension, and attach to the forums (if you hover your mouse over the quote icon in the upper right of one of your existing posts, then other icons will show up…the paper clip icon is for file attach).
You might also want to mention which L4T release you have (run “head -n 1 /etc/nv_tegra_release”), and which remote desktop software you installed.
